Interarc Quadrangle - Calculator
Calculations at an interarc quadrangle. This is formed, when between two equal sized
circles with a distance from each other, two points on the same semicircle are connected with the according opposite points on the other circle. The interarc quadrangle is made of these connections and the enclosed arcs. So it is an isosceles trapezoid, with lateral removed circular segments. If the circles touch, see interarc triangle.
Enter two of the three values from circle radius, distance of the centers and distance between the circles, as well as two of the three values from height of the first and second line and height of the interarc quadrangle. Choose the number of decimal places, then click Calculate.
Construction of an interarc quadrangle.
a = b + 2r
j = h + i
l = 2 * ( r - √ r² - i² ) + b
m = 2 * ( r - √ r² - j² ) + b
α = asin( j / r ) - asin( i / r ), α in rad
n = α * r
k = r * [ 1 - cos( α / 2 ) ]
s = 2 * √ 2 * r * k - k²
p = l + m + 2n
A = ( l + m ) / 2 * h - r * n + s * ( r - k )
Radius, heights, lengths and perimeter have the same unit (e.g. meter), the area has this unit squared (e.g. square meter).
